Subject: ARM: dts: imx6q-tbs2910: add SATA PHY configuration
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c2f303c2635600b9062053b6d7c78be42a018f63;p=linux-beck.git

ARM: dts: imx6q-tbs2910: add SATA PHY configuration

Configure SATA PHY transmit level, boost, attenuation and equalizer
parameters for long wire connections. TBS2910 contains a standard SATA
connector, so devices are typically connected with (longer) SATA cables.
And explicitly configuring these parameters avoids complaints about
"not specified" values in boot messages.
